Boil-off gas handling from liquefied hydrogen storage
, 2020 The main objective of the thesis was to develop concepts for hydrogen boil-off gas reliquefaction. Three different processes were simulated, analyzed, and compared: helium Brayton refrigeration cycle with two helium turbine expanders, hydrogen Claude refrigeration cycle with two hydrogen expanders, and Brayton refrigeration cycle with two expanders for

Use of cryogenic buoyancy systems for controlled removal of heavy objects from the seabed
, 2009 The concept design of a lightweight cryogenic marine heavy lift buoyancy system has been investigated. The approach makes use of a novel cryogenic system for provision of buoyancy within the ocean environment. The objective is to be able to lift or lower

Advanced Sustainable Systems, EarlyView.This study analyses the uncertainty and variability existing in the economic performance of polylactic acid (PLA) production, via integrating techno‐economic analysis with process models and Monte Carlo simulation enabled by artificial intelligence. The results show that the minimum selling price varies from $2,107 to $3076/t PLA.

Annexin A13 Protects Against Acute Kidney Injury by Inactivating TGF‐β/Smad3 Signaling
Advanced Science, EarlyView.ANXA13 is negatively regulated by Smad3 and exerts its protective role in AKI by inactivating TGF‐β/Smad3 signaling and Smad3‐p21 cell cycle arrest pathway through binding to TβRI, inhibiting the interaction between TβRI and TβRII, thereby suppressing TβRI phosporylation.

Fluorescence detection of single lithium atoms in an optical lattice using Doppler-cooling beams
, 2017 We demonstrate in situ fluorescence detection of $^7$Li atoms in a 1D optical lattice with single atom precision. Even though illuminated lithium atoms tend to boil out, when the lattice is deep, molasses beams without extra cooling retain the atoms ...

NFS1 Regulates IDH2 to Attenuate Abdominal Aortic Aneurysms via Interacting With SP2
Advanced Science, EarlyView.The loss of NFS1 leads to its reduced binding with the transcription factor SP2, resulting in decreased expression of the downstream gene Idh2. This causes a shift in energy supply toward glycolysis in VSMCs, ultimately contributing to the occurrence and progression of AAA.
